VEHICLE-WHEEL HUB.

SPECIFICATION forming part of Letters Patent No. 630,883, dated August 15, 1899.

Application filed August 29, 1898.

To all wltont z'f may concern:

Be it known that I, JOSEPH HARTSHORN, a citizen of the United States, residing at Stuart,in the county of Guthrie and State of Iowa, have invented a new and useful Vheel Hub and Lubricator, of which the following is a specification.

The object of this invention is, iirst, to provide a hub for vehicle-wheels which may be and preferably is made of metal and in which the wooden spokes may be quickly and easily introduced and then firmly clamped or secured in place; and in this connection myv object is, further, to provide means whereby any shrinkage in the spokes tending to cause them to rattle in their mortises may be compensated for and the rattling prevented.

A further object is to provide a hub of this class in which a quantity of lubricating-oil may be stored and automatically fed to the wearing-surfaces of the hub and axle and the admission of dust, dsc., to said wearing-surfaces prevented.

My invention consists in certain details of construction, arrangement, and combination of parts, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawing, in which is shown a side elevation of the hub in place on an axle and having its upper portion above the indicated line .x Qs shown in vertical section.

Referring to said drawing, I have employed the reference-numeral 10 to indicate that portion of the vehicle-axle shown, having a nut l1 on its end, all of the usual kind.

The hub proper is composed of the metal axle-bon 12, having an exterior screw-thread at its outer end and an oil-opening 13. On the inner end of the axle-box a hub-section 14E is secured, which section has the usual outer contour of a hub and is provided with mortises 15 for the spoke-tenons 16. This section extends only to the outer edge of said mortises, thus leaving said mortises open for the admission of tenons from the outer edge. A concentric circular groove 17 is formed in the outerface of this hub-section for purposes hereinafter made clear.

The reference-numeral 18 is used to indicate a clamping-collar internally screw-threaded to engage the outer surface of the axle-box Serial No. 689,81'7l (No model.)

The outer end portion of to rigidly connect the collar with said hulo- 6o section, as required to prevent the collar from rotating relative to the hub-section. An annular shoulder produced at` the outer end and circumference of the collar by a further reduction of the diameter allows a packingring to be placed thereon contiguous to an oil-chamber in the outer section of the hub, as required to produce au oil-tight joint between the collar and the outer section of the hub. A second hub-section 2l is fitted to the 7o outside face of the collar 1S to cover and conceal the screws 2O and is screwed to the outer end portion of the axle-box and has an internal chamber 22 formed therein and in position to communicate with the oil-opening 13.

An oil-opening 23 provides access to the interior of this chamber, and a screw 24 is used to close this latter-opening and prevent the entrance of dust. A nut 25 is screwed to the end of the axle-box and is shaped to form the 8o outer. end of the hub. In its outer face are two openings 2G, designed to admit a spanner, whereby it may be turned on the axleboX. A washer 27 is provided at the inner end of the axle-box to engage the axle and prevent the escape of oil or the admission of dust to the wearingsurfaces,and a like Washer 28 is placed on the annular shoulder at the outer end of the collar 1S. By this means a quantity of oil may be kept in the chamber within the hub and automatically fed to the wearing-surfaces.

In practical use it is obvious that the parts of the hub may he quickly and easily assembled and that the spokes will be firmly held in place and prevented from being drawn out by means of the bead or rib 19. The co'llar 18 is prevented fromloosening by means of the screws 20, which prevent its turning oil is provided within the hub and dust is excluded from the wearing-surfaces. In order on the axle-box. Furthermore, a reservoir for roo to detach a ivhe'el from the axle, Vit is necessary rstto remove the hub-section'or nut 25 with a spanner. Then the nut on the end of the axle may be removed to release the Wheel. This is useful in preventing unauthorized persons from removing the Wheel.

Having thus described-my invention, what I claim as new therein, and desire to secure by Letters Patent of the United States therefo isf l. In a Wheel hub and lubricator, a collar having a reduced diameter at its outer end, bores in its inner andlargest end portion and an annular bead on its inner face in direct combination with a hub-section having a*A grooveon its inner face to admit said annular bead on the collar and screw-seats coincidingvith said bores in the collar, mortises in the said hub-section, spokes having grooves coinciding with the groove in the hub-section and set-screws extended through the boresin the collarinto thescreW-seats inthehub-section, and asecond hub-section fitted to the out-side lface of the collar to cover said'screws,

small end for a packing-ring,'a hub-section having an internal screw itted to the outer end of the collar and provided With an oilchamber, a screw-threaded bore intersecting said chamber, a screw fitted in the bore, a packing-ring on the annular shoulder'at the outer end of the collar and a nut or cap havposes stated.

Y 3. A-n improvedvehicle-hub comprising an axle-box having an oil-hole therein,la hub; section havin g spoke-mortises at its outer face' i fixedto the box, a collar secured to the box and designed to engage the spoke-tenons in said mortises, ahub-section secured to the box and having an oil-chamber therein'to communicate With the said-oil-hole, for the purposes stated.

4. An improved vehicle-hub comprising an axle-box having an oil-hole"therein, a hubsection' having spoke-mortises'at itsouterface fixed to fthe'box, a collar secured "to-thefbo'x and' designed to engage the spoketenonsjin said mortises, a hub-section secured to fthe box and having an oil-chamber 'therein to communicate with the said oil-hole, 'and `a hub-section or nut's'c'rewed totheioute'rend of the axle-'boxto'cover'the endof fthe axle and to keep the aforesaid hub-sectionlinpl'ace for the "purposes stated.

5. Animproved vehicle-hub comprising an axle-box having an oil-hole'therein and screwthreaded on its exterior, a hub-seetion-xhaving spoke-inortises at its outer face, andlalsoa groove therein, a collar designed tobe screwed to the axle-box and havinga bead or rib onits inner face, a screw for securing it yto the rst hub-section, a secondhub-section "screwed to the axle-boxand having an oilichaniber therein to communicate with said oil-hole, vandfallso an openin g leading to the oil-chamber,'me'ans for stopping said hole, and a'nuttocover/'the outer end of the axlescrewedtothe aile-box substantially as and .for'the purposesfstated.
